Ad Blocking Detector

Description

Feature: Built-in Tool

Publishers can serve alternative content that appears when users have enabled an adblocker. Ad Blocking Detector will intelligently determine which to display to the user. Check Screenshots tab for examples.
Use this tool to feature content such as a sign-up form for your email newsletter in the place of a blocked ad. Don’t let adblockers waste prime real estate on your site.

Feature: Hook In With JavaScript and CSS

Easily modify the appearance of your site with CSS or execute JavaScript code based on adblock detection results.

Additional Features:

Detects all major adblocking browser extensions on all major web browsers. Including AdBlock, AdBlock Plus, and Ghostery.

At this time, this plugin does not treat disabled JavaScript as an adblocker.
If the visitor has JavaScript disabled, the plugin displays the content used
for normal visitors with no adblockers.

Does this plugin prevent visitors with an adblocker from visiting my site or in any other way obscure the content?

It was not designed to do so, but it is possible to replicate that behavior in an indirect way.
This plugin’s purpose is to simply places alternative content in the space the ad would have displayed.

Why doesn’t this plugin detect the _______________ adblocker?

Not all adblockers operate the same way. This plugin was tested with the most common adblockers, but it is possible one was missed. If you find an adblocker this plugin doesn’t detect, visit the Report a Problem tab in the plugin’s dashboard
for information on testing and reporting undetected adblockers.

Can this plugin integrate with other ad management plugins?

This plugin recognizes shortcodes from other sources. Some ad management plugins use
shortcodes to output their ads. You can use the shortcode generated by other plugins inside Ad Block Detector, allowing you to display ads from ad management plugins while harnessing the power of adblock detection.

Immediately broke the site with this error:
Fatal error: Internal Zend error - Missing class information for in /home/content/73/13183273/html/wp-content/plugins/ad-blocking-detector/views/admin-views.php on line 8
I had to go in via FTP to disable it. Just FYI.

I'd just like to offer my thanks and appreciation to the author of this wonderful plugin!
Simple to setup and works instantly ("plug in and play" I call it) after you've implemented the necessary code into your theme.
Great, great, great! Thanks.
